Smallest tank

The two fish side by side

Fish	Adult size	Temperature	Min. tank	Keep	Watch for
Betta (male)	2.5 in	76–82°F	5 gal	Alone or as a pair	long fins
Mystery snail	2 in	68–82°F	5 gal	Alone or as a pair	invertebrate

Set the heater to about 79°F, in the middle of the range they share (76–82°F).
Use a tank of at least 5 gallons. Check the numbers with the stocking calculator.
Have a backup plan. Every betta has its own temper, so keep a spare tank or divider ready in case it attacks.
Add plenty of plants and cover so every fish can get out of sight.

For bettas: Amano shrimp, Corydoras (bronze or peppered), Ember tetra, Harlequin rasbora, Neon tetra, Nerite snail
For mystery snails: Fancy goldfish, Amano shrimp, Angelfish, Black skirt tetra, Bristlenose pleco, Cardinal tetra
